'Modern Family' sneak peek: James Marsden strips down for hot tub time

“X-Men” star James Marsden brings beefcake to “Modern Family” Wednesday night as he takes on the role of the best-looking hot tub trespasser Mitchell and Cameron have ever seen.

When little Lily’s dads spot an interloper going for a steamy dip in their own backyard, they consider calling the authorities. They then get a better look at newbie Barry and decide 911 isn’t necessary.

Watch Marsden’s “Modern Family” debut Jan. 5 at 9 p.m. ET on ABC.
